機房在沒有屏蔽的情況，電子設備若受到雷擊等強電磁干擾源的影響，將會導致設備無法工作或出現異常，嚴重時甚至出現損壞小百姓网www.xbaixing.com。那麼屏蔽機房的屏蔽效能有哪些種類?
靜電屏蔽：防止靜電耦合干擾，在靜電屏蔽時，屏蔽導體必須接地，屏蔽踢和接地線都是具有良好導電性能的金屬材料小_百_姓_网。
電磁屏蔽：防止高平電磁波干擾，在電磁屏蔽時，屏蔽體本身可以不接地，但為避免發生靜電耦合，電磁屏蔽導體一般也做接地處理小~百~姓~网。
磁屏蔽：防止低頻的磁場感應，在磁屏蔽時，屏蔽體是否接地不影響屏蔽效能，但為了防止靜電感應，屏蔽體一般都接機殼欢迎www.xbaixing.com。

What are the shielding effectiveness of the shielded room?
Electrostatic shielding: Prevent electrostatic coupling interference. In the case of electrostatic shielding, the shielding conductor must be grounded. The shielding kick and the grounding wire are all metal materials with good electrical conductivity.
Electromagnetic shielding: to prevent high-level electromagnetic interference, in the electromagnetic shielding, the shielding body itself can not be grounded, but in order to avoid electrostatic coupling, the electromagnetic shielding conductor is generally also grounded.
Magnetic shielding: Prevents low-frequency magnetic field induction. When magnetic shielding, whether the shielding body is grounded does not affect the shielding effectiveness, but in order to prevent static induction, the shielding body is generally connected to the casing.
